Item 4.  Changes in Registrant's Certifying Accountant

     At the Company's Annual Meeting on May 28, 2003, the Company's shareholders
ratified the recommendation of the Board of Directors to dismiss its independent
accountant, Sanford H. Feibusch, CPA, PC and to appoint BDO Seidman, LLP ("BDO")
as its independent accountants, effective May 28, 2003, for the fiscal year
ended December 31, 2003.

     In connection with his services to the Company in the fiscal year ended
December 31, 2002, Mr. Feibusch prepared (i) a report dated February 5, 2003 on
the Company's consolidated financial statements for the four months ended
December 31, 2002 and 2001, and for the period from November 10, 1997 (date of
inception) to December 31, 2002, and (ii) a report dated November 7, 2002 on the
Company's consolidated financial statements for the years ended August 31, 2002
and 2001, and for the period from November 10, 1997 (date of inception) to
August 31, 2002.  Neither report contained an adverse opinion or disclaimer of
opinion nor was either qualified or modified as to uncertainty, audit scope, or
accounting principles.  Both opinions were qualified, however, as to the
Company's ability to sustain itself as a going concern without securing
additional funding.  In addition, with respect to each of the reports, there
were no disagreements with Mr. Feibusch on any matters of accounting principles
or practices, financial statement disclosure, or auditing scope or procedures,
which disagreements if not resolved to the satisfaction of Mr. Feibusch would
have caused him to make reference thereto in his report on the financial
statements for such periods.

     The Company provided Mr. Feibusch with a copy of the foregoing disclosures
and requested that he furnish a letter addressed to the Securities and Exchange
Commission stating whether or not he agrees with the above statements. A copy of
such letter, dated May 28, 2003 is filed as Exhibit 16 to this Form 8-K.

     In March, 2003, the Company engaged BDO to perform an audit of New Age
Staffing, Inc. ("New Age") which the Company has proposed to acquire. New Age is
currently a privately owned company and is not subject to the reporting
requirements of the Securities Exchange Act of 1934.

     In the course of its relationship with BDO, the Company decided to engage
BDO as its new independent accountants as of May 28, 2003, subject to the
signing of a definitive engagement letter.

     During the two most recent fiscal years and through May 28, 2003, the
Company has not consulted with BDO regarding either (i) the application of
accounting principles to a specified transaction, either completed or proposed;
or the type of audit opinion that might be rendered on the Company's financial
statements, and neither a written report was provided to the Company or oral
advice was provided that BDO concluded was an important factor considered by the
Company in reaching a decision as to the accounting, auditing or financial
reporting issue; or (ii) any matter that was either the subject of a
disagreement, or a reportable event.

Item 5.  Other Events

     Pursuant to a resolution adopted by the Company's Board of Directors on
May 8, 2003 and the affirmative vote of a majority of the shares of the
Company's common stock present or represented at the Company's Annual Meeting on
May 28, 2003, the Company changed its name to Crdentia Corp.

     An amendment to the Company's Amended and Restated Certificate of
Incorporation was filed with the State of Delaware on May 30, 2003 to reflect
this name change.
